This paper traces the development of two 1978 acts--the Pregnancy Discrimination Act and the Age Discrimination in Employment Act Amendment--and identifies some adverse effects that each can be expected to have on the work force in school districts. Besides providing new protection to two classes of workers (the pregnant and the 45-and-over), the paper claims the acts will reduce job opportunities in the schools for qualified candidates. The role of school administrators is to assure that no children suffer from low quality instruction as a consequence of pregnant or aging employees, and at the same time assure these employees that they will not be victims of bias when their performance is evaluated. Other topics covered by the paper include disputes, cases, and congressional testimony about pregnant employees and aging workers. The paper concludes that several new restrictive obligations of employment are now in place and must be incorporated into the thinking and practice of school administrators who deal with personnel management.
